Application inea october 23, ieaaf semi No.7'5eefi5i.

To all 'to/710m t may concern Be it known land Rd., Purley, in the County. of Surrey, England, have invented certain new and useful Improvements in Fastenings, of whichv the following is a specification. y

This invention relates to fastenings of the lstud-and-eye type of the lrind in whichfthe female member fis formed .in two parts hav.- ing relative movement.' p

According to the invention, one part 'of the said female member is provided with means such as spring fingers adapted to .engage beneath the head of the stud, and the second part of vthe said member is provided with means adapted to operate the said stud-engaging means on a relative axial movement of the two parts by means of a surface formed on one of the operative elements which is inclined to the aXis of thel said member.A y f The accompanying drawing illustrates two alternative embodiments of this invention by F ig. l shows a vertical central an assembled fastening. Y

Figs. 2 and 3 show sections of the two elements of the female member when freed.

Fig. 4L showsa plan of one. element, and Figs. 5 and 6 illustrate modifications.

proved fastening comprises a'headed-stud l of the one part which is here Lshown as' mounted on a piece of fabric which may form part of a glove, garment, vehicle hood or the like. .'The female member of the other part comprises a circular 'cup-shaped body 2 also ymounted on a piece `of fabric,

and having an upper inturned rim 3, andthe engaging and operating elements 41, 5 -of the fastening housed within said body. i Referring now to the tiret-mentioned element 4, the engaging element' comprises an i verted cup-shapedmeinber provided on itsy edge ywith a numberof downwardly-extending lingers 6 having turned ends 7 adapted to engage beneath the head of the stud l. The fingers are each provided with an inwardly-inclined portion 6a adjoining an outwardly-extending shoulder 6b andterminating in a bent or looped portion 6C serving to f increase the resiliencewithwhich the inturned end'7 is supported. AThe lingers 6 tend normally to open so'as to release they head of the stud owing to the resilience of' their base portions; but they that I, JOHN PHILIP MORSE, held kinengagement therewith in the posia British subject, residing at Trelaske, Highp turned up ends 8a vthe `body 2, being section of of the housing 2 and are positively tion fsliown by meansA that will be hereinafter described; Intermediate said lingers, themember felis provided with a second series of spring fingers or tongues Shaving for a! purpose that will hereinafter appear. f

, The'V operating member 5 is generally cliannel-shapedfin crosssection', and is adapted toslide axially of the fastening-within prevented vvfrom separation by the inturned rim 3 of saidbody and the out-turned rim 9 on theV said member 5.

lhe inner'wall of the member 5 is provided with an inturned flange l0 which -is provided with three slots 1l for the reception of the fingers 8. The latter thus a'ord guides for. the correct positioning and movement of the member within the member 5, and the ends?a of thesaid fingers are turned up after thesaidV parts have been fitted and thereafter serve as retaining means to prevent the 'separation of the two members. lntermediate the said slots, the flange l0 is small portion l2 of the flange l0, being, however, left inso'as to serve as operating means for the yfingers 6 as is 1.v kThe ends ofthesaid portions 12 engage with the outwardly-extending shoulders 6b Referring now to the Figs. l to l, the im-` clearly shown in Fig.

whereof the faces are soinclined that the two members ofthe female elements of the fastening are self-locking as against vibration or slight pressure, it beingl required to '.eXert an appreciable amount of force tocause the portions "l2 to become disengaged from the ,shoulder 6b in the process of urilocking the fastening.` rEliek cuter lwall of the member 5 is provided with iiiturned spring lingers 13 adapted to rest on thefloor for the movement-of the member 5.

It will be seen that when the female element ofthe fastening is desired to be engaged with the'stud, all: that is necessary is to pressit overthe head of the stud, whereupon the spring fingers 6 willbe forced apart by the said head suciently to enable the fastening togbe pressed home, the resilient loops 6c of the fingers 6 permitting the endsV T'to, be deflected 'ane neath the head of the stud where they will bemaintained in engagement by thefiingers l2. lf then'` it is-desired to release the fastening, all that is necessary is to depress toY .passIV beserve as return springs y resilience of their base portionsv into the position shown in .Fig 2 where they are out of engagement with Vthe head of the stud which can then be withdrawn, the. part 5v reassuming the position shown in Fig. 1

immediately it is freed. lt' will of course be apparent that in the release operation described, any movement of the member 4L induced by the release movement of the member 5 will be interrupted-by the fingers 7 engaging the base plate of the body 2, whereupon the member 5 continues its movement for the release action.

It is to be observed that fany attempt forcibly to withdraw the fastening without operating the releasing member will be chiefly resisted by the shearing strength of the inturned ends 7 of the fingers 6 engaging between the underside of the stud and the circulaiedge of the centre orifice 14 of the base plate 15 of the cup-shaped member 2.

This provides a strongresistance without tending to deform any of the operative parts of the mechanism in a manner that would malte it no longer serviceable. The looped portions 6 in the fingers 6 provide a resilient means whereby, when themember 5 is forced downwardly and the fingers 12 are forced past the edges of the shoulders 6b, the said shoulders can move inwardly without permanently defer-ming the fingers '6 in the-event of the ends 'T being held fixed by \the stud 1, They also serve to inter-pose a resilient element between the male and female members of the fastening so as to avoid 1o permanent deformation of any of the parts incase of relative lateral movement.

It will be further noted that when the part 5 moves up into its normal position followingrthe release of the ngers 7, the

portion 12 of thepart 5 will engage the inclined portion 6b of the fingers and will thereafter move the central part 4- upwardly with it to thefull` extent of movement, as the frictional engagement betweenthe part 5o 12 and the part 6l is sufficient to overcome the gravitational infiuence on the part el. The central partl will thus protrude upwardly from the annular part 5, and when it is desired tore-engage the stud, the part 4L will have tokbe positively depressed so as to bring thek portion 6a thereof to the same level as the part 12 of the member 5.

In a modification, l may substitute an annularL ring for, the operating fingers 12 as shown in Fig. 5.

The modification illustrated in Fig. G r omprises a simplified model w ierein the loops 6C of the lingers 6 are dispensed with, and the fingers 8 and fla-nge 1() are also dispensed with, upwardly-extending lugs 16 on the outer wall of the member l1 engaging in slots 17 in the inner wally of the member 5 serving to limit the movement of the member 5. The operating fingers 12 are four in number and are inclined downwardly as shown and intermediate the fingers G in the member 4 are provided intervening lingers 18 adapted to rest on the head of the stud so normally as to urge the member 1l upwardly.

1t will be realized that in both modifications the operation of the fa tening depends upon an axial movement of one element of the female member operating through. an inclined surface on the stud-engaging means. In both forms i shown the smul-engaging means are positively held in engagement with the stud and swing outwardly therefrom of their own resilience when released by the operating means.

Although pr'marily intend-ed to be formed by press tools out of sheet metal, it .is lo be understood that this material is not essential to the invention, and l may form the fastening of such a size and strength that a lock can ber mounted within the cup-shaped annular member and eperated through a keyhole faeing upwardly in the drawing so as to force lateralbolts through the engaging rims 3 and 9 and through vthe engaging walls of the members 1- and 5 so as to lock the fastening in .itsl operative position.
